Question

a. Why is ice at 273 k more effective in cooling than water at the same temperature?​

Answer 1

Answer:

- At 273 K, ice absorbs more heat than water from the substance to overcome the latent heat of fusion and thus providing a more effective cooling effect. Water however does not absorb any extra heat from the substance. Thus, ice is more effective in cooling than water at 273 Kelvin.

Answer 2

Answer:

Ice at 273 K is more effective in cooling than water at same temperature because ice at 273 K absorbs more heat than water as it has passed the latent heat of fusion and can be an effective cooling agent.
